Old flames Sumner Redstone and Christine Peters appeared to rekindle their romance over the holiday weekend, starting Friday night at Il Piccolino in West Hollywood. According to one eavesdropper, the Viacom and CBS chairman and the blond ex-wife of producer Jon Peters discussed Redstone’s Super Bowl experience and Peters’ upcoming film projects — she produced “How To Lose a Guy in Ten Days” for Redstone’s Paramount Pictures. Elton John and David Furnish, dining at a nearby table, dropped over to visit. Redstone and Peters were blitzed by paparazzi as they exited. The shutterbugs then raced down the street to capture Brad Pitt and Angelina Jolie and their kids at Benihana. On Valentine’s Day, Redstone and Peters, who dated before his last marriage, celebrated Chinese New Year at CBS Seafood Restaurant in LA’s Chinatown. A Redstone rep denied any romance and said he and Peters are “just friends.”
